Quantum optics

The tiny diamond pyramid tips used for atomic force microscopy may also prove to be highly useful for nanoscale, quantum sensing

Using a crystal to link visible light to infrared
opens a window on infrared sensing

A quantum effect allows infrared measurements to be performed by detecting visible light, bringing opportunities for cheaper, better performance spectroscopy

Quickly switching the orientation of a laser beam enables control over the quantum properties of light

Ultrafast laser pulses and precisely cut optical crystals could control the quantum properties of light
